In our invention We mak these leaserods ofmetal and insulate them from the loom-frame in order to permit us to usethem es the content rods or terminals of ein electric oieuit. As hereinshown, seid-rods are snp:-

We have herein shown in Figs. 6 and 7 two different forms ofcrcuit-closcrs- In Fi l6 each circuit-closer has two open inclined s ots16 and Yl?, which extend inwardly from the same side of thecircuit'cioser and prei'ernhiy 'diverge from 4each other,V The slotf inthe vother slot Ii'jeeeives the supporting-rod 14.

We rn'j,"Y use this forni of circuit-closer nt hoththe iront and rearhunks, of we may use the form of circuit-closer shown in Fig. T n1therear henk, as shown in Fig, 8. in Vif; T the circuit-closer has theopen sint. lo n: its outer or heavy end, which sint tormmm-s in, an eye71, throuffh which 't he warp-z mnil 1S passes, and the coscd slm, Tltin-Hugh which the supportingzfrod 14 passes. The reason These parts maye for making the circuit-closersof the forms herein shown will bereferred to later. The

. circuit-elosers are hung on the lower plane or level oftheWarp-threads, and theirpoint'of suspensibn is outside of the lease-rods,as plainly` shown in Fig. 6. Said circuit-closers and the wa threads andare situated outare theref; entirely below the lease-rods side of theease-rods, where there is more,

room for `there 'to work without danger of chafing adjacent threadslEach circuitcloser 1s provided withatail portion 19, which serves twopurposes-first, as a means for contacting with one of the lease-rods 6,and thus closing the circuit when a warp-thread breaks, and, second, asan indicator to indicate to the operator the location of the brokenthread, as will be more fully hereinafter described.

One of the brackets v7h is Aconnected by a suitable wire 21'and withabattery 22 or 'other source of electrical energy, and said eewi fthemechanism whc shipper to stop the loom.

battery is connected by another suitable wire t an electroma et 26,forming part of cooperates with the he stop mechanism which wel haveherein illustrated comprises the ma et 26, supported an arm 27 ofasuitab e bracket 28, carried by the loom-frame and a tappet 29, which iscontrolled by the magnet and which operates to disengagp theshipper-lever from its lockin notch w en the clrcuitjs closed by thebrea ing of a warp-thread. We prefer to pivotal ly mount the tappet 29upon the same bracket Whichsupports the magnet, and for this purposehave formed said racket with a second arm 30, on which Vthe tap etisfpivotally mounted. The tappet is in t e vertical plane oftheshipper-lever, and when said lever is in its notch one end of the tappetis adjacent the lever. The La pet is so balanced and elow the plane'of asuitable bunter 32, cari {cised that nornraly its outer epd 31 standsred by the lay, so that as the lay beats up said bunter 32 passes overthe end 31 of the tappet, as shown in dotted lines, Fig. 1. The

' opposite end of the tappet is over the magnet fio -., from theloom-frame, to the battery or other ourse of electrical supplv by meansof-tbe coils of the magnet by means of the wire 23. From the ma net thecircuit is completed through the oom-frame and the circuitclosers, thelatter being supported by the brackets 9, which are connected directlyto the loom-frame, and are therefore electrically connected with saidframe, but insulated from the lease-rods 6 so long as the warps remainunbroken.'

The operation of our device will be apparbe energized. vAs soon'as'thisoccursthe tappet 29 is'thrown into its operative position by the magnet,and' yupon the n'e'xtforward movement of the lay the shi per-lever isdisengaged from its notch. T entails 19'of the circuit-closers arepurposely made longer than is necessary to contact with the leaserods,so that whenany one has swung into abnormal position its tail is thrownup above i I the level o he warp-threads, thus an indicator,whichlocates the 'place where i the break has occurred.

We have also provided means in connection with our warp stop mechanismwhereby the circuit is broken as soon as the shipperlever is thrown outof its notch, thereby saving the energy of the battery or other sourceof electrical supply after the loom has been stopped. We accomplish thisby connecting the wire 23,leading from the magnet 26,'to agravity-finger 40, which is ivoted on a stud and carried by but insulatefrom the bracket 28 and which lies against the shipper-lever 5 when thelatter is in its locking-notch; as shown in Fig. 9, With thisconstruction the circuit is closed by the finger 40 when theshipper-lever is in its locking-notch, but as soon as the lever has beend iseng 'ed from the notch the circuit is broken at t is place. Weprefer the. gravity-actuated Engler 40 rather than a spiling-fixiger,because t e latter is very apt to ct bent, so that itwill not contactwith the sghipper-lever when the latter'is'in its locking-notch. Theavity-aetuated .inger isfree from this ob]ection and the closing of thecircuit is always insured at this point when the shipper is in operativeposition. Y

41 desi natos a brace which extends across between t elower branches 42of the brackets 9 and is adjustably connected thereto. Said lesv14,.Whil e the same closets of the rear braccioli/tries arms 43, (seedotted lines, Fig. 6,) throu h which tho supporting-rods poss end whicserve to sustmn seid rods intermediate their ends und hold them inproper position.

tion in which the warp-threads are drawn from the loom-beam, and thecircuit-closers 'at the right of scid iirure constitute, therefore, therear bank oi? circuitclosers, while those at the left constitute thefront bank. To prevent the circuibclosers from boinga thrown olf fromthe supporting-rods 14 by the u and-down movement of the werp-Y threa s,due to the shedding motion, we prefer to eniploy guard-rods 20, whichextend across above the circuit-closers and are cerf ried by the wings13 of the brckets'il'.' 'The forward movement of the werp-threads in thedirection of the arrow a, Fig. 6, will b Y their friction with thecircuibciosers 'of'bot banks tend to draw the circuit-closers forwardlyor in the direction of seid arrow,nnd u on referring to saidgure it willYbe seen t et any forward movement of Vthe' circuitclosers of tl.: frontbenk will tend to seat them r'nore rinly on their supporting-rodmovement e the circuitbank will tend todsconl neet them from theirsupportingrod., To prevent en of the rear bank of circling-clos-Y ersfrom t usi-becoming disconnected .from the supporting-rod 14, weprefecto ilse the additional guard-rod 38 beneath seid circuitolosers,which, togethewith thcguard 20, prevents said circuit-closets from beingdrawn 0E fromV the rod-14. it is unnecessary to employ a ard-rod 38 forthe 'circuit'- closets 'of the ont bsnk,'elthough such rod ma' be"used,if desired.

n Fig. 7 we have 'illustrated s. slightl different form fcircuit-closer, which can e used at the rear bank, said o ircuitolnsersbeing lconstructed so that they canrfot become dislodged from thesupporting-rod 14. In this form of circuitwloser' the slot 17, in whichthe supporting-rod 14 is received, is a closed slot, so that after thecircuit-closers are threaded onto said rod it will be impossible forthem to bc dislodged. The 'form pf y circuit-closer shown in Fig. 7 hasthe suppleL s id rod *,lius operating to correctly rnentalpositioning-notch' 74, which is utilized while the circuit-closers arebeing npplied to the loom.' During such operation the cireuit-closersare hung over the wer threads 18, and the notch 74 of each closerisidroppcrl onto a. positionmg-rod '75, iosition al of thecirouit-closers and bring t ie slotsV 17 thereof into ailinvernent,s iIthat the supporting-rod 14 .inaybe inserted through seid' alined slots.v

If desiued, the lease-rods may be made ln Fig. 6 the arrow a designatesthe direcwith the flattened portion 7l, as shown in Fig. 8, againstwhich the toil oi the circuitcloser contacts, thus mnkingo more extendVed contactssurfnce than is possiblrl where the lease-rod is round.

There are several points about our method ol' supporting thecircuit-closure to which we desire to cell attention.

the circuit-closers are located entirely below It will be noted that thewerp-,threads and are surpported by the l lower level thereof outside othe lease-rods, and the pivotal points of the circuit-closers are suchwith relation to the lesse-rods that when the circuit is closed the teilof the eircuit-closer contacts with the side othe leescrod whieh'is freefrom any lint. The oircuitciosers crc placed below the warp-threads andnre suspended on the lower plaines or levels thereof, and are thereforeentirely out of the wey of' the loom attendent and do not interfere inany way with the ordinary o eration of the loom. ,Seid circuit-closets,owever, are so constructed that whenever s defeet oecursjin anwerpthread the corresponding circuitpc oser swings into abnormal sitionand not only stops the loom, but of' itself indicatesthc point'where thebreak has ooourred,thus materially saving the time of.

the 'attendent in repairm the defect, The eircuitfcloserssre suspen edfrom the wur threads on the outside of the lease-rods. This is ofmaterial advantage, because oi the comparative ease' with y. which thecircuitclosers een be epplied to the warp-threads. Wherethecircuit-closers are supported on the werphresds between Vthelease-rods, the s ece in'which the operator con work in putY ting thecircuit-closets into position is very much restricted, whilewhere seidcircuit closers are supported outside of the lease-rods their; aplication to the warp threads y.is greatly aciliteted The position ofthe slots 15, Y17, and 17 in the circuit-closers and the position ofthecircuit-closers with relation to the lease-rods are such that eachcircui t-closer has to fal a considerable distance before its tail isbrought into contact with the lease4 rodsnd the circuit is closed. Thisconstruction obviates the possibility o the circuit 'being closed whenany warp-thread becomes slsekencd somewhat, but not broken.

Another important point in our invention which wedesire tofempliosize isthat the ordinery lease-rods @of the leoni are used as thejterminals ofthe circuit including the loom-stopping mechanism, `and 'therefore nospecial oontctfrod separate from the leaserodsl has to be empio ed tocooperate with the crcuit-elosers. i he device is such that it een beapplied to any ordinary loom by simply removing. the lease-rods andplacing suitable metal ease-rods (which constitute contact-rods) in thebrackets 7, which brack- ICO ets are suitably supported from vtheloomframe. The leaserods 6 therefore have two functions-first, the usualfunctions of aleaserod, and, second, the function of a contactrodterminal of a controlling-circuit.

While we ha'e shown herein one embodiment of our invention, we do notwish to bc limited to the exact forin and arrangement of the partsshown, as these may be varied in many ways without departing in any wayfrom the-invention, which is pointed out in the appended claii s.
